    Conquering the Paper and Pen Challenge: A Physics-Based Solution

    Hello ! My friend challenged me to remove a sheet that is under a standing pen, without the pen falling. I can only use 2 finger and i can only touch the paper. Do you know a way to do this ? (he said that I have to use physics)
